Description

Technical Field

[0001] The present invention relates to the technical field of display devices, and in particular, to a display device and a method for adjusting picture quality parameters of a display device. Background Art

[0002] With the upgrading of display devices, users have more requirements for the display picture quality of display devices. For example, terminal devices with image processing functions such as mobile phones, tablet TVs, and smart TVs can, after obtaining original images such as pictures or videos, adjust parameters such as the brightness, contrast, chromaticity, and sharpness of the original images, so that the adjusted images present a picture quality effect that can improve the user's viewing experience.

[0003] In some implementation solutions for adjusting picture quality parameters of display devices, the display device opens some image parameters for users to adjust according to their needs. For example, the user can open the settings application of the display device, and then adjust parameters such as brightness, contrast, chromaticity, and sharpness in the picture quality adjustment sub-item in the settings application, so that the picture presented by the display device better meets the user's own viewing needs.

[0004] However, the specific implementation method of the above implementation solution for adjusting picture quality parameters is as follows: pull up a specific image parameter menu, and then select the image parameter to be adjusted for adjustment. However, this adjustment method requires pulling up an image parameter setting floating window, and then adjusting the image parameters in the pulled-up floating window. If other parameters need to be set, other parameter setting floating windows need to be pulled up again. And if the image menu has multiple levels of menus, when switching the parameters to be adjusted, it is necessary to switch in the multiple levels of menus. These will all result in complicated operation steps for adjusting picture quality parameters. Summary of the Invention

[0005] The present application provides a display device and a method for adjusting picture quality parameters of a display device, which solve the problem of complicated operation steps in the current implementation method for adjusting picture quality parameters.

[0006] In a first aspect, some embodiments of the present application provide a display device, including:

[0007] A display configured to display a user interface;

[0008] A controller configured to:

[0009] Obtain an adjustment instruction for indicating picture quality adjustment input by a user, where the adjustment instruction is an instruction input by the user based on the application interface of a color adjustment application, and the color adjustment application is a third-party application for adjusting picture quality;

[0010] If the display device stores at least one picture quality adjustment template, in response to the adjustment instruction, display identification controls corresponding to at least one picture quality adjustment template on the display, where the picture quality adjustment template includes at least two picture quality parameters;

[0011] In response to a selection instruction input by the user indicating to select a first identification control corresponding to a first picture quality adjustment template, adjust the picture quality of the user interface by using the picture quality parameters included in the first picture quality adjustment template;

[0012] If the display device does not store a picture quality adjustment template, in response to the adjustment instruction, display a prompt message on the display, where the prompt message is used to prompt the user that the display device does not currently store a picture quality adjustment template.

[0013] In a second aspect, some embodiments of the present application provide a picture quality adjustment method for a display device, which is applied to a display device, and the display of the display device is configured to display a user interface. The picture quality adjustment method of the display device includes:

[0014] Obtain an adjustment instruction input by the user indicating to adjust the picture quality, where the adjustment instruction is an instruction input by the user based on the application interface of a color adjustment application, and the color adjustment application is a third-party application for adjusting the picture quality;

[0015] If the display device stores at least one picture quality adjustment template, in response to the adjustment instruction, display identification controls corresponding to at least one picture quality adjustment template on the display, where the picture quality adjustment template includes at least two picture quality parameters;

[0016] In response to a selection instruction input by the user indicating to select a first identification control corresponding to a first picture quality adjustment template, adjust the picture quality of the user interface by using the picture quality parameters included in the first picture quality adjustment template;

[0017] If the display device does not store a picture quality adjustment template, in response to the adjustment instruction, display a prompt message on the display, where the prompt message is used to prompt the user that the display device does not currently store a picture quality adjustment template.

[0018] As can be seen from the above technical solutions, the display device and the image quality adjustment method of the display device provided in the above embodiments obtain an adjustment instruction for indicating the adjustment of the image quality, and the adjustment instruction is an instruction input by the user through a third-party application for adjusting the image quality. If the display device stores at least one image quality adjustment template, in response to the adjustment instruction, an identification control corresponding to at least one image quality adjustment template is displayed on the display, and the image quality adjustment template includes at least two image quality parameters. In response to a selection instruction indicating the selection of a first identification control corresponding to a first image quality adjustment template input by the user, the image quality of the user interface is adjusted by using the image quality parameters included in the first image quality adjustment template. In this way, the image quality of the user interface can be batch-set by using the image quality parameters pre-set in the image quality adjustment template, reducing operations such as pulling up a floating window or switching through multiple levels of menus, thereby simplifying the operation steps for adjusting the image quality parameters.

[0045] To make the objectives, technical solutions and advantages of the present application clearer, the exemplary embodiments of the present application and the corresponding drawings will be used to clearly and completely describe the exemplary implementation manners of the present application. Obviously, the described exemplary embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0046] It should be noted that the brief description of the terms in the present application is only for facilitating the understanding of the following described implementation manners, rather than intending to limit the implementation manners of some embodiments of the present application. Unless otherwise specified, these terms should be understood according to their ordinary and general meanings.

[0047] The terms "first", "second", "third", etc. in the description, claims and the above-mentioned drawings of the present application are used to distinguish similar or like objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that such terms can be interchanged under appropriate circumstances.

[0048] The terms "comprising" and "having" and any variations thereof are intended to cover but not exclude inclusion. For example, a product or device including a series of components does not necessarily have to be limited to all the clearly listed components, but may include other components that are not clearly listed or are inherent to these products or devices.

[0049] The display device provided by the implementation manner of the present application can have various implementation forms. For example, it can be a television, a smart TV, a laser projection device, a monitor, an electronic bulletin board, an electronic table, etc.

[0050] Figure 1 and Figure 3 A specific implementation manner of the display device of the present application.

[0051] Figure 1 A schematic diagram of the operation scenario between the display device and the control device in the exemplary embodiment of the present application. As Figure 1As shown, the user can operate the display device 200 through the mobile terminal 300 and the control device 100.

[0052] In some embodiments, the control device 100 can be a remote control. The communication between the remote control and the display device includes infrared protocol communication or Bluetooth protocol communication, and other short - range communication methods, and controls the display device 200 wirelessly or wiredly. The user can input user instructions through the buttons on the remote control, voice input, control panel input, etc. to control the display device 200.

[0053] In some embodiments, a smart device 300 (such as a mobile terminal, a tablet computer, a computer, a laptop, etc.) can also be used to control the display device 200. For example, an application program running on the smart device is used to control the display device 200.

[0054] In some embodiments, the display device can receive user control not by using the above - mentioned smart device or control device, but by touch or gesture, etc.

[0055] In some embodiments, the display device 200 can also be controlled in ways other than the control device 100 and the smart device 300. For example, it can directly receive the user's voice command control through a module for obtaining voice commands configured inside the display device 200, or receive the user's voice command control through a voice control device set outside the display device 200.

[0056] In some embodiments, the display device 200 also conducts data communication with the server 400. The display device 200 is allowed to communicate and connect through a local area network (LAN), a wireless local area network (WLAN), and other networks. The server 400 can provide various contents and interactions to the display device 200. The server 400 can be a cluster, or multiple clusters, and can include one type or multiple types of servers.

[0057] Figure 2 Exemplarily shows a hardware configuration block diagram of the control device 100 according to an exemplary embodiment. As Figure 2 shown, the control device 100 includes a controller 110, a communication interface 130, a user input / output interface 140, a memory, and a power supply. The control device 100 can receive the user's input operation instructions, and convert the operation instructions into instructions recognizable and responsive by the display device 200, acting as an interaction intermediary between the user and the display device 200. As Figure 3 shown, the display device 200 includes at least one of a tuner - demodulator 210, a communicator 220, a detector 230, an external device interface 240, a processor 250, a display 260, an audio output interface 270, a memory, a power supply, and a user interface.

[0058] In some embodiments, the processor includes a video processor, an audio processor, a graphics processor, RAM, ROM, and a first interface to an nth interface for input / output. The display 260 includes a display screen component for presenting a picture, and a driving component for driving image display, a component for receiving an image signal from the output of the processor, and a component for displaying video content, image content, and a menu control interface, as well as a user control UI interface. The display 260 can be a liquid crystal display, an OLED display, a projection display, or a projection device and a projection screen.

[0059] The communicator 220 is a component for communicating with external devices or servers according to various communication protocol types. For example, the communicator can include at least one of a Wifi module, a Bluetooth module, a wired Ethernet module, other network communication protocol chips such as a near-field communication protocol chip, and an infrared receiver. The display device 200 can establish the sending and receiving of control signals and data signals with the external control device 100 or the server 400 through the communicator 220.

[0060] The user interface can be used to receive control signals from the control device 100 (such as an infrared remote control, etc.).

[0061] The detector 230 is used to collect signals from the external environment or for external interactions. For example, the detector 230 includes a light receiver, a sensor for collecting ambient light intensity; or, the detector 230 includes an image collector, such as a camera, which can be used to collect external environmental scenes, user attributes, or user interaction gestures. Or, the detector 230 includes a sound collector, such as a microphone, etc., for receiving external sounds.

[0062] The external device interface 240 can include, but is not limited to, the following: a high-definition multimedia interface (HDMI), an analog or data high-definition component input interface (component), a composite video input interface (CVBS), a USB input interface (USB), an RGB port, or any one or more of these interfaces. It can also be a composite input / output interface formed by the above multiple interfaces.

[0063] The tuner demodulator 210 receives broadcast television signals through wired or wireless reception, and demodulates audio and video signals from multiple wireless or wired broadcast television signals, such as EPG data signals.

[0064] In some embodiments, the processor 250 and the tuner demodulator 210 can be located in different separate devices, that is, the tuner demodulator 210 can also be in an external device of the main device where the processor 250 is located, such as an external set-top box, etc.

[0065] The processor 250 controls the operation of the display device and responds to user operations through various software control programs stored in the memory. The processor 250 controls the overall operation of the display device 200. For example, in response to receiving a user command for selecting a UI object to be displayed on the display 260, the processor 250 can perform operations related to the object selected by the user command.

[0066] In some embodiments, the processor includes at least one of a central processing unit (CPU), a video processor, an audio processor, a graphics processing unit (GPU), a random access memory (RAM), a read-only memory (ROM), a first interface to an nth interface for input / output, a communication bus, etc.

[0067] The user can input a user command on the graphical user interface (GUI) that can be displayed on the display 260, and then the user input interface receives the user input command through the graphical user interface (GUI). Alternatively, the user can input a user command by inputting a specific sound or gesture, and then the user input interface receives the user input command by recognizing the sound or gesture through a sensor.

[0068] The "user interface" is a media interface for interaction and information exchange between an application program or an operating system and a user, and it realizes the conversion between the internal form of information and the form acceptable to the user. The common manifestation form of the user interface is the graphical user interface (GUI), which refers to the user interface related to computer operations displayed in a graphical manner. It can be an interface element such as an icon, a window, a control, etc. displayed on the display screen of an electronic device, where the control can include visible interface elements such as an icon, a button, a menu, a tab, a text box, a dialog box, a status bar, a navigation bar, a widget, etc.

[0069] As Figure 4 shown, the system of the display device is divided into three layers, namely the application layer, the middleware layer, and the hardware layer from top to bottom.

[0070] The application layer mainly includes common applications on the TV and an application framework. Among them, the common applications are mainly applications developed based on the browser, such as HTML5 APPs; and native applications (Native APPs).

[0071] The Application Framework is a complete program model that has all the basic functions required by standard application software, such as file access, data exchange..., and the usage interfaces for these functions (toolbars, status bars, menus, dialog boxes).

[0072] Native APPs can support online or offline, message push or local resource access.

[0073] The middleware layer includes various middleware such as TV protocols, multimedia protocols, and system components. The middleware can use the basic services (functions) provided by the system software to connect various parts of the application system on the network or different applications, and can achieve the purpose of resource sharing and function sharing.

[0074] The hardware layer mainly includes the HAL interface, hardware, and drivers. Among them, the HAL interface is the unified interface for all TV chips to dock, and the specific logic is implemented by each chip. The drivers mainly include: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor drivers (such as fingerprint sensors, temperature sensors, pressure sensors, etc.), and power drivers, etc.

[0075] When using a display device, the user can adjust the picture quality of the display device. For example, by adjusting parameters such as the brightness, contrast, chroma, and sharpness of the original image, the image after picture quality adjustment can present a picture quality effect that can improve the user's viewing experience. In some implementation solutions for adjusting the picture quality parameters of display devices, the display device opens some image parameters for the user to adjust according to their needs. The specific implementation method of the implementation solution for adjusting the picture quality parameters in the related technology is: open the picture quality setting menu in the system settings, then select the image parameter to be adjusted, and pull up the setting floating window of the image parameter.

[0076] such as Figure 5As shown, if the user needs to adjust the "black level", the user needs to select "black level". After the system receives the user's selection instruction, a setting floating window for "black level" is pulled up, and the user can adjust the picture quality parameter of "black level" in the setting floating window of "black level". If the user needs to adjust the "contrast", the floating window of the picture quality parameter of "black level" needs to be closed first, and then the floating window of the picture quality parameter of "contrast" is pulled up. It can be seen that if there are multiple levels of menus in the image menu, when switching the parameters to be adjusted, it is necessary to switch in the multiple-level menus. All these will result in complicated operation steps for adjusting picture quality parameters. For the display device 200 that needs to be controlled by a remote controller, the user may need to repeatedly press the up button, down button, left button, right button and return / confirm button on the remote controller to implement the picture quality adjustment function, which significantly increases the operation difficulty of the user to adjust the picture quality.

[0077] In view of the above problems, some embodiments of the present application provide a picture quality adjustment method applied to a display device 200. To facilitate the understanding of the technical solutions in some embodiments of the present application, each step will be described in detail below with reference to some specific embodiments and drawings. Figure 6 It is a schematic flowchart of a picture quality adjustment method executed by a display device 200 provided in some embodiments of the present application.

[0078] As Figure 6 shown, the controller 250 in some embodiments of the present application is configured to execute the following steps:

[0079] Step S601, obtain an adjustment instruction indicating picture quality adjustment input by the user, where the adjustment instruction is an instruction input by the user through a color adjustment application, and the color adjustment application is a third-party application for adjusting picture quality.

[0080] The adjustment instruction indicating picture quality adjustment in the present application is an instruction input by the user through a color adjustment application, which is different from the setting application of the system. The color adjustment application is a third-party application for adjusting picture quality. The relationship between the color adjustment application and the setting application is as Figure 7 shown. The setting application can adjust the picture quality of the user interface. For example, in the user interface as Figure 5 shown, after the user adjusts a single picture quality parameter, the adjusted picture quality parameter is sent to the picture quality parameter adjustment platform, and the picture quality parameter adjustment platform is a processing module for the actual effect of the display picture quality. After the user adjusts the picture quality parameter in the color adjustment application interface, the adjusted picture quality parameter is also sent to the picture quality parameter adjustment platform, and the picture quality parameter adjustment platform performs data processing on the picture quality parameter and makes the adjusted picture quality parameter reflected on the picture of the user interface.

[0081] The parameter communication method between the setting application and the color adjustment application can be customized, which is specifically implemented through the AIDL (Android Interface Definition Language): the color adjustment application registers data monitoring with the setting application through the RegisterPictureCallback (IPictureInfo info) function. Users can adjust the image quality parameters in real time through the setting application. When the setting application adjusts the image quality parameters in real time, on the one hand, the adjusted image quality parameters are sent to the image quality parameter adjustment platform to realize the image quality parameter display, and on the other hand, the adjusted image quality parameters are returned to the color adjustment application through IPictureInfoinfo. Users can also adjust the image quality parameters in real time through the color adjustment application. The color adjustment application implements image quality parameter management. On the one hand, based on the registered data monitoring, the current image quality parameters are cached. On the other hand, the image quality parameter control and adjustment interface is provided to the business layer. Based on the provided image quality parameter interface, the image quality parameters can be synchronized to the image quality of the entire machine.

[0082] If the user calls out the system's setting application to adjust the image quality, the batch image quality parameter adjustment method of the present application is not applied. If the user calls out the color adjustment application to adjust the image quality, the batch image quality adjustment method of the present application is applied. The method of calling out the system's setting application may be to pop up an application window of the setting application on the display after receiving an operation of pressing a setting button on the remote control input by the user. The method of calling out the color adjustment application may be to pop up an application window of the color adjustment application on the display after responding to a selection instruction of selecting an application icon of the color adjustment application input by the user.

[0083] like Figure 8 The user interface shown in the figure can place the application icon of the color adjustment application and the application icon of the setting application together, so that if the user needs to adjust the image quality, he can select the color adjustment application or the setting application as needed. If the user clicks the application icon of the color adjustment application, the application window of the color adjustment application pops up on the display; if the user clicks the application icon of the setting application, the application window of the setting application pops up on the display.

[0084] In some embodiments, when the display device 200 is displaying any content, if the display device 200 has a built-in intelligent voice interaction system, the user can input voice content such as "adjust image quality" or "image quality parameters", and the display device 200 responds to the voice issued by the user such as "adjust image quality" and pops up an application window of the settings application or an application window of the color adjustment application. The specific application window can be popped up according to the application used by the user last time or the application used more frequently. For example, if the image quality adjustment application used by the user last time is the settings application, or the image quality adjustment application used more frequently is the settings application, after responding to the voice issued by the user, the application window of the settings application can be popped up; if the image quality adjustment application used by the user last time is the color adjustment application, or the image quality adjustment application used more frequently is the color adjustment application, after responding to the voice issued by the user, the application window of the color adjustment application can be popped up.

[0085] The user can also directly input voice content such as "color adjustment application" or "color adjustment", and the display device 200 responds to the voice issued by the user such as "color adjustment application" and pops up a color adjustment application window, and displays the application interface of the color adjustment application in the color adjustment application window.

[0086] Step S602, if the display device 200 stores at least one image quality adjustment template, in response to the adjustment instruction, display identification controls corresponding to at least one of the image quality adjustment templates on the display, where the image quality adjustment template includes at least two image quality parameters.

[0087] After a color adjustment application window is popped up on the display, it is necessary to first determine whether the display device 200 stores an image quality adjustment template. All the image quality adjustment templates in the embodiments of the present application include at least two image quality parameters. The display device 200 in the embodiments of the present application depends on the image quality support ability of the image quality adjustment platform and can customize the image quality parameter list shown in Table 1. It should be noted that the image quality parameters in Table 1 are only exemplary displays, and the user can add or delete the image quality parameters in the image quality adjustment template according to the needs in the color adjustment application platform.

[0088]

[0089] Table 1 Image quality parameter list of the color adjustment application

[0090] The image quality adjustment template in the embodiments of the present application includes at least two of the image quality parameters in Table 1, for example, includes two image quality parameters of contrast and black level, or includes three image quality parameters of contrast, black level, and color temperature, and can also include all the image quality parameters in Table 1.

[0091] If the display device 200 stores at least one image quality adjustment template, such asFigure 9 As shown, at least one identification control corresponding to a picture quality adjustment template is displayed on the display. For example, if the picture quality adjustment template 1 is stored in the display device 200, the identification control corresponding to the picture quality adjustment template 1 is displayed on the display; if the picture quality adjustment template 1 and the picture quality adjustment template 2 are stored in the display device 200, the identification control corresponding to the picture quality adjustment template 1 and the identification control corresponding to the picture quality adjustment template 2 are displayed on the display.

[0092] On the display device 200, a record table related to the picture quality adjustment template of the color adjustment application can be set, and the names of the picture quality adjustment templates already stored on the display device 200 can be recorded in the picture quality adjustment template record table. That is to say, the names corresponding to the picture quality adjustment templates stored on the display device 200 are all recorded in this picture quality adjustment template record table, while the names corresponding to the picture quality adjustment templates not stored on the display device 200 will not be recorded in the picture quality adjustment template record table. If the picture quality adjustment template stored on the display device 200 is deleted, the name corresponding to the deleted picture quality adjustment template will also be removed from the picture quality adjustment template record table.

[0093] Based on the above principle, when it is necessary to call a picture quality adjustment template, it can be judged whether the display device 200 stores a picture quality adjustment template according to the picture quality adjustment template record table. For example, if the name of the picture quality adjustment template is not recorded in the picture quality adjustment template record table, it means that the display device 200 does not store the picture quality adjustment template. If the name of the picture quality adjustment template is recorded in the picture quality adjustment template record table, it means that the display device 200 stores the picture quality adjustment template. If the name of one picture quality adjustment template is recorded in the picture quality adjustment template record table, it means that the display device 200 stores one picture quality adjustment template; if the names of two picture quality adjustment templates are recorded in the picture quality adjustment template record table, it means that the display device 200 stores two picture quality adjustment templates...

[0094] After judging that the display device 200 stores at least one picture quality adjustment template, in response to the adjustment instruction for indicating to adjust the picture quality input by the user, at least one identification control corresponding to the picture quality adjustment template is displayed on the display. Correspondingly, if only one picture quality adjustment template is stored in the display device 200, only one identification control corresponding to the picture quality adjustment template is displayed on the display. If the display device 200 stores multiple picture quality adjustment templates, only one identification control corresponding to the picture quality adjustment template can be displayed on the display, or multiple identification controls corresponding to the picture quality adjustment templates can be displayed on the display.

[0095] Step S603, in response to the selection instruction for indicating to select the first identification control corresponding to the first picture quality adjustment template input by the user, adjust the picture quality of the user interface by using the picture quality parameters included in the first picture quality adjustment template.

[0096] If at least the first image quality adjustment template is stored in the display device 200, at least the first identification control corresponding to the first image quality adjustment template is displayed on the display. If a selection instruction for selecting the first identification control is received, in response to the selection instruction, the image quality of the current user interface is adjusted by using the image quality parameters included in the first image quality adjustment template.

[0097] For example, the first image quality adjustment template includes image quality parameters: contrast +60, blue gain +20, green gain +1, red gain +50, etc. If the user selects the first image quality adjustment template, the contrast, blue gain, green gain, and red gain of the current user interface are adjusted according to the image quality parameters of the first image quality adjustment template. If the image quality parameters of the current user interface are contrast +50, blue gain +20, green gain 0, red gain +50. According to the image quality parameters of the first image quality adjustment template, the contrast needs to be increased from +50 to +60, and the green gain also needs to be increased from 0 to +1, while the blue gain and red gain remain unchanged.

[0098] If the image quality is not adjusted by using the first image quality adjustment template, the user needs to separately pull up the floating window of the contrast, increase the contrast from +50 to +60 by pressing the plus key, then exit the floating window of the contrast, pull up the floating window of the green gain, and increase the green gain from 0 to +1 again by pressing the plus key. It can be seen that the image quality adjustment operation in the related technology is relatively complicated for the user, while the present application can batch-adjust at least two image quality parameters by using the image quality adjustment template, thus simplifying the image quality adjustment operation.

[0099] Step S604, if the display device does not store an image quality adjustment template, in response to the adjustment instruction, a prompt message is displayed on the display.

[0100] If it is determined that the display device 200 does not store an image quality adjustment template, for example, after searching the image quality adjustment template record table, the name of the image quality adjustment template is not found, it is determined that the name of the image quality adjustment template is not recorded in the image quality adjustment template record table, indicating that the display device 200 does not store an image quality adjustment template. At this time, a prompt message indicating that there is no stored image quality adjustment template can be displayed on the display. The user can perform the next operation according to the prompt message, for example, re-selecting to use the settings application for image quality adjustment.

[0101] As can be seen from the above technical solutions, for the display device 200 and the image quality adjustment method of the display device 200 provided in the above embodiments, an adjustment instruction for indicating image quality adjustment input by the user is obtained, and the adjustment instruction is an instruction input by the user through a third-party application for adjusting image quality. If the display device 200 stores at least one image quality adjustment template, in response to the adjustment instruction, an identification control corresponding to at least one image quality adjustment template is displayed on the display, and the image quality adjustment template includes at least two image quality parameters. In response to a selection instruction indicating selection of a first identification control corresponding to a first image quality adjustment template input by the user, the image quality of the user interface is adjusted using the image quality parameters included in the first image quality adjustment template. In this way, the image quality of the user interface can be batch-set using the pre-set image quality parameters in the image quality adjustment template, reducing operations such as pulling up a floating window or switching through multiple levels of menus, thereby simplifying the operation steps for adjusting the image quality parameters of the screen.

[0102] In some embodiments, in response to a selection instruction indicating selection of a first identification control corresponding to a first image quality adjustment template input by the user, adjusting the image quality of the user interface using the image quality parameters included in the first image quality adjustment template may include:

[0103] In response to a selection instruction indicating selection of a first identification control corresponding to a first image quality adjustment template input by the user, an image quality parameter display window corresponding to the first image quality adjustment template is displayed on the display, where the image quality parameter display window includes at least an OK button control. The user can input an OK instruction for determining to use the first image quality adjustment template by clicking the OK button control. If an OK instruction indicating determination to use the first image quality adjustment template input by the user is received, in response to the OK instruction indicating determination to use the first image quality adjustment template, the image quality of the user interface is adjusted using the image quality parameters included in the first image quality adjustment template.

[0104] If an adjustment instruction for adjusting the image quality parameters included in the first image quality adjustment template input by the user is received, in response to the adjustment instruction for adjusting the image quality parameters included in the first image quality adjustment template, the image quality parameters of the first image quality adjustment template are adjusted. Then, in response to an OK instruction indicating use of the first image quality adjustment template after adjusting the parameters input by the user, the image quality of the user interface is adjusted using the image quality parameters included in the first image quality adjustment template after adjusting the parameters. That is to say, the user can confirm to use the image quality parameters of the first image quality adjustment template to adjust the image quality of the user interface based on the image quality parameter display window of the first image quality adjustment template. The user can also adjust the image quality parameters included in the first image quality adjustment template based on the image quality parameter display window of the first image quality adjustment template, and then use the first image quality adjustment template after adjusting the image quality parameters to adjust the image quality of the user interface. In this way, based on the selected first image quality adjustment template, the user can further adjust the image quality parameters so that the adjusted image quality better meets the user's viewing needs.

[0105] For example, as Figure 10 shown in the user interface is the picture quality parameter display window corresponding to the first picture quality adjustment template. The picture quality parameter display window corresponding to the first picture quality adjustment template shows the picture quality parameters included in the first picture quality adjustment template: picture quality parameters such as contrast, clarity, color temperature, etc. In Figure 10 the shown user interface, if the user clicks the OK button control, in response to the operation input by the user, the picture quality of the user interface is adjusted by using the picture quality parameters included in the current first picture quality adjustment template, that is, the picture quality parameters included in the current first picture quality adjustment template are applied to the overall picture quality of the machine.

[0106] In Figure 10 the shown user interface, the user can move the focus on different picture quality parameter labels by pressing the up button, down button, left button, and right button on the remote control. For example, move the focus to the picture quality parameter label of the green level. After the focus falls on the picture quality parameter label of the green level, the user can press the OK button on the remote control to input an instruction indicating to determine the adjustment of the green level picture quality parameter. At this time, if the user continues to press the up button on the remote control, the focus no longer moves to other picture quality parameter labels, but increases the green level. For example, on the basis of the green level being +20, upon receiving the operation of the user pressing the up button on the remote control, in response to the operation instruction to increase the green level, the green level is increased from +20 to +30. If the user continues to press the up button on the remote control, the green level is continuously increased from +30 to +40.

[0107] If the user needs to adjust other picture quality parameters, after determining the adjustment of the green level picture quality parameter, the user can input an instruction indicating to cancel the adjustment of the green level picture quality parameter by pressing the OK button on the remote control twice in a row. At this time, if the user presses the direction key on the remote control, the focus will move to other picture quality parameter labels. For example, pressing the up button on the remote control moves the focus to the contrast picture quality parameter label. Similarly, the user can press the OK button on the remote control to input an instruction indicating to determine the adjustment of the contrast picture quality parameter. At this time, if the user continues to press the down button on the remote control, the focus no longer moves to other picture quality parameter labels, but decreases the contrast. For example, on the basis of the contrast being +50, upon receiving the operation of the user pressing the down button on the remote control, in response to the operation instruction to decrease the contrast, the contrast is decreased from +50 to +40. Finally, the first picture quality adjustment template after adjusting the parameters is obtained as Figure 11 shown. Based on the first picture quality adjustment template after adjusting the parameters, if the operation of the user clicking the OK button control is received, in response to this determination operation, the picture quality of the user interface is adjusted by using the picture quality parameters included in the Figure 11 shown first picture quality adjustment template after adjusting the parameters.

[0108] In some embodiments, the adjustment instruction may further carry the number of adjustments of the picture quality parameters, where the number of adjustments is the number of items of the picture quality parameters that the user inputs and needs to adjust. If the number of adjustments is greater than or equal to two, in response to the adjustment instruction, at least one identification control corresponding to the picture quality adjustment template is displayed on the display; if the number of adjustments is less than two, in response to the adjustment instruction, the application interface jumps from the adjustment application to the application interface of the settings application, so that the user can adjust the picture quality of the user interface based on the settings application, and the settings application is a system for at least adjusting the picture quality. That is to say, before displaying the identification control corresponding to the picture quality adjustment template, the number of picture quality parameters that the user needs to adjust can be determined, and only when the number of items of the picture quality parameters to be adjusted reaches two, the picture quality adjustment template is used for picture quality adjustment.

[0109] For example, an inquiry dialog box can be configured in the application window of the color adjustment application to inquire about the number of picture quality parameters that the user needs to adjust. If the number of picture quality parameters input by the user in the inquiry dialog box is one, the application window can jump to the settings application, and then the settings application is used to adjust a single picture quality parameter (the operation of the settings application for adjusting a single picture quality parameter is more convenient). If the number of picture quality parameters input by the user in the inquiry dialog box exceeds one, for example, 6 are input, the application window of the color adjustment application can be kept displayed, and then the color adjustment application is used to adjust multiple picture quality parameters (the method of using the picture quality parameter adjustment template of the color adjustment application to adjust the picture quality is more convenient for adjusting multiple picture quality parameters). In this way, the settings application or the color adjustment application of the system can be called according to the actual usage requirements of the user, so that the picture quality adjustment function of the display device 200 is more widely applied.

[0110] In some embodiments, when adjusting the picture quality of the user interface by using the picture quality parameters included in the first picture quality adjustment template, it is equivalent to applying the picture quality parameters included in the first picture quality adjustment template to the overall picture quality of the machine. Therefore, the display device 200 applies the first picture quality adjustment template to the whole machine. The picture quality parameters included in the settings application also reflect the current overall picture quality of the display device 200. Therefore, after adjusting the picture quality of the user interface by using the picture quality parameters included in the first picture quality adjustment template, the picture quality parameters included in the first picture quality adjustment template need to be sent to the settings application, so that the settings application can adjust the corresponding picture quality parameters according to the picture quality parameters included in the first picture quality adjustment template.

[0111] For example, after Figure 11 adjusting the overall picture quality based on the first picture quality adjustment template shown, the picture quality parameters of the first picture quality adjustment template are sent to the settings application, and the settings application is based on Figure 11 After updating the picture quality parameters according to the picture quality parameters included in the first picture quality adjustment template in, it gets as Figure 12The picture quality parameters included in the application interface of the shown settings application. Figure 12 The values of the picture quality parameters included in the shown settings application are exactly the same as Figure 11 the values of the picture quality parameters included in the shown first picture quality adjustment template. In this way, if the user further adjusts the overall picture quality of the display device using the settings application, the adjustment can be based on the current latest overall picture quality of the display device. If such synchronous update adjustment is not made, after adjusting the overall picture quality using the first picture quality adjustment template, the picture quality parameters included in the settings application are not the current latest overall picture quality of the display device, which may cause the settings application to be unable to adjust the picture quality properly. After synchronously updating the picture quality parameters of the first picture quality adjustment template to the settings application, the user can then use the settings application to further adjust the picture quality normally.

[0112] Similarly, if the user uses the settings application to further adjust the overall picture quality based on the picture quality parameters of the first picture quality adjustment template, it is also necessary to send the first picture quality parameters adjusted on the settings application to the color adjustment application. The color adjustment application adjusts the values of the first picture quality parameters in the first picture quality adjustment template according to the adjusted values of the first picture quality parameters. For example, after adjusting the overall picture quality of the display device using the picture quality parameters of the Figure 11 shown first picture quality adjustment template, the user then reduces the contrast from +40 to +30 through the settings application. At this time, it is necessary to synchronize the reduced contrast value to the color adjustment application. The color adjustment application adjusts the contrast value in the first picture quality adjustment template according to the received reduced contrast value, and finally obtains the Figure 13 shown first picture quality adjustment template. This not only synchronizes the picture quality parameters of the color adjustment application with those of the settings application, but also enables the user to further modify the picture quality parameters of the color adjustment application through the settings application, making the picture quality adjustment effect of the picture quality adjustment template of the color adjustment application more in line with the user's viewing needs.

[0113] The above process of picture quality parameter adjustment can be applied to the scenario where the display device 200 is currently playing an image, or to the scenario where the display device 200 is not currently playing an image. If the display device 200 is not currently playing an image, in the Figure 14 shown user interface, corresponding effect thumbnails can be displayed on one side of each picture quality adjustment template. The effect thumbnails corresponding to different picture quality adjustment templates can use the same picture, for example, use the same landscape picture. In this way, the user can intuitively view the effects of different picture quality adjustment templates on the same picture after picture quality adjustment, making it easier for the user to select the picture quality adjustment template they need. The user can also replace the original picture in the effect thumbnail.

[0114] For example, before playing a science fiction movie, the user adjusts the picture quality of the display device 200. The original picture in the thumbnail can be replaced with a picture with a science fiction background, or the original picture in the thumbnail (the picture can be dynamic) can be directly replaced with a clip of the upcoming science fiction movie. In this way, the user can more easily determine which picture quality adjustment template is more suitable for the science fiction movie. Before playing an animated movie, the user adjusts the picture quality of the display device 200. The original picture in the thumbnail can be replaced with something related to the animated movie, or the original picture in the thumbnail can be directly replaced with a clip of the upcoming animated movie. In this way, the user can more easily determine which picture quality adjustment template is suitable for the animated movie.

[0115] Here, the color adjustment application can judge the upcoming video or the currently playing video according to the current system time and the program schedule list, and then judge the thumbnail that needs to be replaced according to the upcoming video or the currently playing video. For example, the current time is 15:45. By retrieving the program schedule list, it can be known that the currently playing TV program is a certain science fiction movie and the end time is 16:45. Therefore, the system can judge that the current user needs to adjust the picture quality for this science fiction movie, so the thumbnail can be replaced with a clip of this science fiction movie. Then, on one side of the identification control corresponding to each picture quality adjustment template, a clip of the science fiction movie after being adjusted by the picture quality parameters included in each picture quality adjustment template is displayed. Therefore, clips of science fiction movies with different picture quality effects are presented on one side of each picture quality adjustment template. The user can select the picture quality adjustment template corresponding to the picture quality effect they need according to these clips of science fiction movies with different picture quality effects. After selecting the picture quality adjustment template, when playing this science fiction movie, the picture quality of this science fiction movie can be adjusted according to the picture quality parameters included in the selected picture quality adjustment template.

[0116] If the display device 200 is currently playing an image screen and the display device 200 is currently in a non-automatic recognition scene mode, such as Figure 15 shown in the user interface, at least one identification control corresponding to the picture quality adjustment template can be randomly displayed on the display, or in the above manner, on one side of the identification control corresponding to each picture quality adjustment template, a preview window of the currently playing image screen (the currently playing image screen is displayed in the preview window) is displayed, and the picture quality of the image screen displayed in the preview window on one side of the identification control corresponding to each picture quality adjustment template corresponds to the picture quality parameters included in each picture quality adjustment template. When the display device 200 is in a non-automatic recognition scene mode, it cannot automatically recognize the picture scene of the current display device 200.

[0117] If the display device 200 is currently playing an image screen and the display device 200 is in the automatic scene recognition mode, that is to say, the display device 200 can currently automatically recognize the screen scene of the display device 200. It should be noted that whether the mode of automatically recognizing the screen scene can be set according to the user. For example, the switch for automatically recognizing the screen scene is set. If the switch for automatically recognizing the screen scene is on, the display device 200 is currently in the automatic scene recognition mode. If the switch for automatically recognizing the screen scene is off, the display device 200 is currently in the non-automatic scene recognition mode. Whether the mode of automatically recognizing the screen scene can also be determined according to the current performance of the display device 200. For example, whether the current display device 200 has the function of automatically recognizing the screen scene. If the current display device 200 does not have the function of automatically recognizing the screen scene, the display device 200 is in the non-automatic scene recognition mode. If the current display device 200 has the function of automatically recognizing the screen scene, the display device 200 is in the automatic scene recognition mode. It should be noted that the above-mentioned screen scene refers to the video screen scene of the image screen being played by the display device 200, which may include a sports screen scene, a movie screen scene, a children's screen scene, etc.

[0118] When the display device 200 is playing an image screen, in response to an adjustment instruction for adjusting the picture quality, in order to recognize the screen scene of the currently played image screen, a screenshot of the currently displayed image screen can be taken. One screenshot or multiple screenshots can be taken. If one screenshot is taken, the currently captured content can be stored in the memory of the display device 200 in the form of a picture, and the scene of the stored screenshot picture can be recognized. The picture scene in the picture can be recognized according to the screenshot picture. The display device 200 is also configured with a corresponding relationship between the picture quality adjustment template and the screen scene. For example, the sports screen scene corresponds to the sports-style picture quality adjustment template, the movie screen scene corresponds to the movie-related picture quality adjustment template (film-style picture quality adjustment template or Hong Kong movie-style picture quality adjustment template), and the children's screen scene corresponds to the cartoon-style picture quality adjustment template.

[0119] If only one screenshot is taken of the playing image, only one frame of the video data being played can be captured, and there may be a situation where the scene judgment of the picture is incorrect. Therefore, to improve the accuracy of scene judgment of the picture, multiple screenshots can be taken of the playing image, so that multiple frames of the video data being played can be captured. It can be multiple consecutive screenshots of the playing image, or multiple screenshots of the playing image at intervals. If the scene of the picture judged based on the multiple captured frames is not exactly the same, the scene of the picture with the most judgment times can be determined as the final scene of the picture. For example, if 6 screenshots are taken of the playing image, 6 frames of the video data being played are captured, and the scene of each of the 6 frames is recognized, and the results of 1 sports scene and 5 movie scenes are obtained, it can be determined that the final scene of the playing image is the movie scene.

[0120] Based on Figure 16 the corresponding relationship between the image quality adjustment template and the picture scene shown, according to the recognized picture scene, the image quality adjustment template required for the currently playing image can be determined. After determining the image quality adjustment template required for the currently playing image, only the identification controls corresponding to the determined image quality adjustment templates can be displayed on the display, and the identification controls corresponding to the undetermined image quality adjustment templates are not displayed, which makes it easier for users to select the image quality adjustment templates that meet their needs.

[0121] Since current display devices 200 all have a split-screen function and can split the screen into two parts or multiple parts according to the user's needs, the screen display ratio of each part after splitting is adjusted according to the user's actual needs, and the application programs displayed on each part after splitting do not affect each other. For example, the user can start a video call on the left and watch a sports live broadcast on the right. However, for such a split-screen scenario, the display device 200 cannot accurately identify the scene of the currently playing image, and thus cannot determine the accurate image quality adjustment template. At this time, the captured screen image includes both the currently playing image (finally, the image quality of the currently playing image actually needs to be adjusted), and the application interfaces of other applications. The application interfaces of other applications may include graphic information and text information.

[0122] Therefore, after obtaining the captured screen image, graphic information and text information can be recognized in the screen image. Among them, the graphic information refers to the set of all image contents appearing in the recognized screen image, and the text information refers to the set of all text contents in the recognized screen image. The graphic information also includes global image information and detailed image information. The global image information refers to classifying all images, such as a person object in the image, and classifying it as a person. The detailed image information refers to making a detailed distinction for all graphics. For example, through an image recognition model, functional icons appearing in the image can be recognized, such as dedicated icons like signal icons and TV channel icons. The image recognition model can be obtained by training an initial model based on "graphic - label" sample data.

[0123] After recognizing the graphic information and text information in the captured screen image, the played image frame can be extracted from the captured screen image. For example, the split - screen applications are a social chat application and a video - playing application. The captured screen image includes the application interface of the social chat application and the application interface of the video - playing application. The application interface of the social chat application includes more text information, and the application interface of the video - playing application includes more graphic information. Therefore, the application interface of the video - playing application can be extracted from the screen image. Then, the screen scene is recognized based on the extracted application interface of the video - playing application, and the corresponding image quality adjustment template is determined according to the recognized screen scene.

[0124] In the split - screen application scenario, it may be necessary to perform different image quality adjustments on different partitions participating in the split - screen. For example, when the split - screen applications are a social chat application and a video - playing application, not only is it necessary to adjust the image quality of the video frame of the video - playing application to make the video frame look better, but also it is necessary to adjust the image quality of the chat frame of the social chat application to make the person image show different styles. Therefore, corresponding image quality adjustment templates can also be configured for the application interfaces of different applications. Establish a set of image quality adjustment templates for different applications in the color - adjustment application. After recognizing different applications, call different image quality adjustment templates and use different image quality adjustment templates to adjust the image quality of the application interfaces of different applications respectively.

[0125] For example, such as Figure 17The user interface shown includes the application interface of Application 1 and the application interface of Application 2. When the user opens the color adjustment application to adjust the picture quality of the current display device, the picture quality can be adjusted respectively based on the application interface of Application 1 and the application interface of Application 2. Specifically, according to the picture quality adjustment template corresponding to Application 1 is displayed on the application interface of Application 1, and the picture quality adjustment template corresponding to Application 2 is displayed on the application interface of Application 2. The user can adjust the picture quality of the application interface of Application 1 based on the color adjustment application interface corresponding to Application 1, and adjust the picture quality of the application interface of Application 2 based on the color adjustment application interface corresponding to Application 2, so as to realize different picture quality adjustment operations on the application interfaces of different applications, and finally different picture quality adjustment effects are presented on the application interfaces of different applications.

[0126] If the display device stores only one picture quality adjustment template, only the identification control corresponding to one picture quality adjustment template is presented. If the display device stores multiple picture quality adjustment templates, the identification controls corresponding to multiple picture quality adjustment templates can be presented, and they can be presented in descending order of the priority of the picture quality adjustment templates. For example, Picture Quality Adjustment Template 1, Picture Quality Adjustment Template 2, Picture Quality Adjustment Template 3, Picture Quality Adjustment Template 4, and Picture Quality Adjustment Template 5 are the picture quality adjustment templates already stored in the display device, and the priorities of Picture Quality Adjustment Template 1, Picture Quality Adjustment Template 2, and Picture Quality Adjustment Template 3 from high to low are Picture Quality Adjustment Template 2 > Picture Quality Adjustment Template 3 > Picture Quality Adjustment Template 1 > Picture Quality Adjustment Template 4 > Picture Quality Adjustment Template 5. Therefore, the picture quality adjustment templates can be presented according to Figure 18 the display effect shown. Among them, due to the interface size limitation, only three picture quality adjustment templates can be presented simultaneously on the application interface of the color adjustment application. Therefore, it is more beneficial for users to select the picture quality adjustment template that meets their needs faster by preferentially displaying the picture quality adjustment templates with higher priorities. The priority of the picture quality adjustment template can be based on the system score of the picture quality adjustment template (the higher the system score, the higher the priority level of the picture quality adjustment template) or the user's historical selection record (the higher the number of times the user has selected a picture quality adjustment template, the higher the priority level).

[0127] The picture quality adjustment applications in the related art can only adjust the picture quality parameters included in the application. For example, as Figure 5 shown in the settings application, only picture quality parameters such as "black level", "contrast", "chroma", "hue", and "sharpness" can be adjusted, and the items of the picture quality parameters cannot be adjusted.

[0128] In view of the above problems, some embodiments of the present application provide a method for generating a picture quality adjustment template applied to a display device 200. For the convenience of understanding the technical solutions in some embodiments of the present application, each step will be described in detail below in combination with some specific embodiments and drawings. Figure 19Schematic diagram of the process of the display device 200 provided by some embodiments of the present application for performing picture quality adjustment. As Figure 19 shown, the controller 250 in some embodiments of the present application is configured to perform the following steps:

[0129] Step S1901, in response to a control instruction input by the user to indicate the opening of a new template window of the color adjustment application, present the new template window of the color adjustment application on the display, where the color adjustment application is a third-party application for adjusting picture quality, the new template window is a window for creating a picture quality adjustment template, and the picture quality adjustment template includes at least two picture quality parameters.

[0130] The control instruction input by the user to indicate the opening of a new template window of the color adjustment application and presenting the new template window of the color adjustment application on the display may include:

[0131] In response to a adjustment instruction input by the user to indicate the adjustment of picture quality, determine whether the display device 200 stores a picture quality adjustment template. If the display device 200 stores a picture quality adjustment template, directly display the stored picture quality adjustment template on the display. If it is determined that the display device 200 does not store a picture quality adjustment template, a prompt message indicating that there is no stored picture quality adjustment template can be displayed on the display. Additionally, while displaying the prompt message, a new creation identification control can also be displayed, such as Figure 20 the user interface shown. The new creation identification control is used to create a picture quality adjustment template, that is, the user can create a picture quality adjustment template by clicking on the new creation identification control. It should be noted that, as Figure 21 shown, if the display device 200 stores a picture quality adjustment template, the stored picture quality adjustment template is displayed on the display, and the new creation identification control can also be displayed. In this way, if the user is not satisfied with the picture quality adjustment effect of the stored picture quality adjustment template, the user can also create a new picture quality adjustment template by clicking on the new creation identification control.

[0132] The user inputs an operation of clicking on the new creation identification control, that is, inputs a control instruction to indicate the opening of a new template window of the color adjustment application. In response to this control instruction, present the new template window of the color adjustment application on the display. As Figure 22 shown, in the new template window, the user can perform the operation of creating a picture quality adjustment template.

[0133] Step S1902, based on the user's operation of adjusting the items and values of the picture quality parameters in the new template window, generate a first picture quality adjustment template and store the first picture quality adjustment template in the display device, so that when it is necessary to adjust the picture quality of the user interface, use the picture quality parameters included in the first picture quality adjustment template to adjust the picture quality of the user interface.

[0134] Figure 22 The newly created template window shown includes multiple default picture quality parameters. For example, after opening the newly created template window, the newly created template window includes default picture quality parameters such as "black level", "contrast", "chroma", "hue", and "sharpness". Users can adjust the values of these default picture quality parameters in the newly created template window, and can also perform removal operations on the default picture quality parameters in the newly created template window (removing the picture quality parameters through the corresponding removal controls). It should be noted that for the removed picture quality parameters, the default values will be used when actually adjusting the overall picture quality of the machine. For example, after removing "contrast" from the newly created template window, the generated picture quality adjustment template will not include the "contrast" picture quality parameter. When actually adjusting the overall picture quality of the machine, it is not that the "contrast" picture quality parameter is not set, but that it is set according to the default value, that is, the "contrast" picture quality parameter in the overall picture quality of the machine is still a parameter with a value.

[0135] When the controller executes a control instruction to open the newly created template window of the color adjustment application in response to a user input instruction, it presents the newly created template window on the display, and at the same time also presents a picture quality parameter library on the display. The picture quality parameter library includes at least two picture quality parameters. Based on the basic picture quality parameters (i.e., default picture quality parameters) included in the newly created template window, picture quality parameters can be selected from the picture quality parameter library and added to the newly created template window (realizing the addition of picture quality parameters through the corresponding addition controls), and the added picture quality parameters can also be adjusted in value. As Figure 23 The user interface shown not only presents the newly created template window, but also presents a picture quality parameter library. The picture quality parameter library includes picture quality parameters not included in the newly created template window: "white balance (specifically including picture quality parameters such as red gain, green gain, and yellow gain)" and "color correction (specifically including picture quality parameters such as red hue, red saturation, and red brightness)". Users can add the picture quality parameters included in the picture quality parameter library but not included in the newly created template window to the newly created template window. In this way, users can adjust the items of the picture quality parameters in the newly created template window according to the picture quality adjustment requirements.

[0136] After completing the operation of generating a new picture quality adjustment template, the new picture quality adjustment template can be saved to the display device 200, and the new picture quality adjustment template can be named. For example, name the new picture quality adjustment template as XX picture quality adjustment template, and then save the name to the picture quality adjustment template record table. After the system detects that there is a name stored in the picture quality adjustment template record table, it determines that there is a picture quality adjustment template stored in the current display device 200, and can automatically use the new picture quality adjustment template to adjust the picture quality of the current user interface. A query dialog box can also be popped up to ask the user whether to apply the new picture quality adjustment template to the picture quality of the current user interface. If an immediate use instruction input by the user is received, the new picture quality adjustment template is used to adjust the picture quality of the current user interface.

[0137] As can be seen from the above technical solutions, the display device and the picture quality adjustment template generation method provided in the above embodiments respond to a control instruction for indicating to open a new template window of a color adjustment application, and present a new template window of the color adjustment application on the display. The color adjustment application is a third-party application for adjusting picture quality, the new template window is a window for creating a picture quality adjustment template, and the picture quality adjustment template includes at least two picture quality parameters. Based on the operation of the user to adjust the items and values of the picture quality parameters in the new template window, a first picture quality adjustment template is generated, and the first picture quality adjustment template is stored in the display device so that when the picture quality of the user interface needs to be adjusted, the picture quality parameters included in the first picture quality adjustment template are used to adjust the picture quality of the user interface. In this way, not only can the picture quality parameters be adjusted in batches using the picture quality adjustment template, but also the items of the picture quality parameters can be adjusted according to the picture quality adjustment requirements, thereby enhancing the diversity of the picture quality adjustment function.

[0138] In some embodiments, before saving the new picture quality adjustment template (the first picture quality adjustment template) to the display device 200, the template type of the first picture quality adjustment template can be determined according to the picture quality parameters included in the new first picture quality adjustment template. The picture quality parameters included in the already stored picture quality adjustment template can be matched with the picture quality parameters included in the first picture quality adjustment template, and the template type of the first picture quality adjustment template can be determined according to the matching result. For example, the picture quality parameters included in the first picture quality adjustment template match the picture quality parameters included in the already stored X picture quality adjustment template, and the template type of the X picture quality adjustment template is the movie type. Therefore, the template type of the first picture quality adjustment template can be determined as the movie type.

[0139] After determining the template type of the first image quality adjustment template, the first image quality adjustment template can be marked according to the determined template type, and then the first image quality adjustment template after marking the template type is stored in the display device 200. When it is necessary to call the image quality adjustment template to adjust the image quality, the image quality adjustment template can be called according to the template type. Specifically, if the display device is currently in the automatic recognition scene mode, in response to the adjustment instruction for adjusting the image quality input by the user, the scene of the image screen currently played by the display device is recognized. When the display device is in the automatic recognition scene mode, it can automatically recognize the scene of the image screen currently played by the display device; according to the scene of the image screen, based on the mapping relationship between the scene of the image screen and the template type, the image quality adjustment template corresponding to the scene of the image screen is searched from the image quality adjustment template library; the image quality of the user interface is adjusted by using the image quality parameters included in the found image quality adjustment template.

[0140] For example, based on the above embodiment, after automatically recognizing the scene of the image screen currently played by the display device, it is determined that the scene of the image screen currently played is a movie scene. Since there is a mapping relationship between the scene of the image screen and the template type, it can be that the scene of the movie scene has a mapping relationship with the template type of the movie type. Therefore, it can be determined that the template type of the image quality adjustment template required for the currently played image screen is the movie type. Since the template type of the newly created first image quality adjustment template is the movie type, the above newly created first image quality adjustment template can be displayed to the user for viewing. If the user determines to select the newly created first image quality adjustment template to adjust the image quality, the image quality of the user interface can be adjusted by using the image quality parameters included in the newly created first image quality adjustment template.

[0141] In some embodiments, when classifying the image quality adjustment template according to the template type of the image quality adjustment template, the classification of the template type can also be refined. For example, the image quality adjustment template of the movie type can be further divided into: classic Hong Kong movie type, cartoon type, film type, etc. This can improve the user's satisfaction with the image quality adjustment effect of the image quality adjustment template.

[0142] After generating a new image quality adjustment template on the display device 200, the newly created image quality adjustment template can also be sent to the server corresponding to the color correction application, and the newly created image quality adjustment template is saved in the server, so that other devices can directly download and use the newly created image quality adjustment template from the server corresponding to the color correction application.

[0143] For example, as Figure 24In the user interface shown, a "Save as Template" control and a "Share" control can be set below the new template window. If the user inputs an operation of clicking the "Save as Template" control, in response to the save instruction input by the user, the newly created picture quality adjustment template is saved in the display device 200. If the user inputs an operation of clicking the "Share" control, in response to the share instruction input by the user, the newly created picture quality adjustment template is saved to the display device 200, and the newly created picture quality adjustment template is sent to the server corresponding to the color grading application, so as to share the newly created picture quality adjustment template for use on other devices.

[0144] In some embodiments, if the display device 200 needs to call a picture quality adjustment template for picture quality adjustment but there is no picture quality adjustment template stored in the display device 200, a request sharing identification control can be displayed on the display. If the user inputs an operation of clicking the request sharing identification control, in response to the selection instruction of the request sharing control input by the user, a picture quality adjustment template request can be sent to the server corresponding to the color grading application. After receiving the picture quality adjustment template request sent by the display device 200, the server corresponding to the color grading application feeds back the picture quality adjustment template to the display device 200 according to the picture quality adjustment template request. After receiving the feedback picture quality adjustment template, the display device 200 can adjust the picture quality of the current user interface by using the picture quality parameters of the picture quality adjustment template fed back by the server.

[0145] In some embodiments, after generating a first picture quality adjustment template based on the user's operation of adjusting the items and values of the picture quality parameters in the new template window, a sharing code corresponding to the first picture quality adjustment template is created, so that a first device can adjust the interface picture quality of the first device by using the first picture quality adjustment template based on the sharing code. The first device and the display device are different devices. In this way, the newly created first picture quality adjustment template can be shared through the sharing code. It should be noted that the sharing code can be in the form of a two-dimensional code or a character code. If the sharing code is in the form of a two-dimensional code, the first device can obtain the first picture quality adjustment template by scanning the two-dimensional code. If the sharing code is in the form of a character code, the first device can obtain the first picture quality adjustment template by inputting the character code.

[0146] In some embodiments, as Figure 25 shown in the user interface, the picture quality parameters included in the new template window can be divided into basic picture quality parameters and advanced picture quality parameters. The user can choose to set only the basic picture quality parameters, or only the advanced picture quality parameters, or choose to set both the basic picture quality parameters and the advanced picture quality parameters at the same time. The basic picture quality parameters and the advanced picture quality parameters set the picture quality parameters by calling different picture quality parameter interfaces. In this way, setting the basic picture quality parameters and setting the advanced picture quality parameters can not only be implemented in a segmented manner but also in a concurrent manner. It should be noted that Figure 25Only one example of the distinction between basic picture quality parameters and advanced picture quality parameters is shown. In actual applications, the basic picture quality parameters and advanced picture quality parameters can be divided differently according to requirements.

[0147] The following is a specific example of generating a picture quality adjustment template, which includes the following steps:

[0148] In the color grading application, establish data communication with the platform picture quality parameter management through the service binding method. Through the getPictureMode interface provided by the platform to obtain the current picture quality mode (i.e., the picture scene). The picture quality modes include: under SDR (Standard Dynamic Range, standard dynamic range image) (standard, vivid, natural children, sports, cinema, game, text), and under HDR (High-Dynamic Range, high dynamic range image) (standard, vivid, children, sports, cinema, game, text). In the color grading application interface, display the clip selection list through the menu. Specifically, through the file traversal method, read the video file list from the local USB flash drive / palette / . Here, the file path is the specified color palette path. Place the video source files of different styles of color palettes according to requirements. The styles include video files of different styles such as film, classic, and sports.

[0149] Based on the displayed style list, you can select a video file of any display style and start video playback through the platform's built-in player. After the video starts playing, obtain the image mode of the currently playing video through the platform interface. For example, if the image mode is HDR, you can obtain the preview list of picture quality parameters related to the HDR mode through the interface provided by the platform to obtain picture quality parameters. For the picture quality parameter selected by the focus, the corresponding content editing prompt box can be displayed. For example, when the focus falls on the contrast, the user can press the OK button on the remote control to pull up the content editing interface corresponding to the contrast. The user can enter the parameter value of the contrast in the content editing interface.

[0150] After the user clicks the OK button on the editing interface and the input value (such as 50) is received by the interface of the color adjustment application, the data is then judged. If the input value is INVALID (indicating that this parameter is ignored and the current parameter value of the platform is adopted). If the input value is invalid, only the image quality data -1000 is displayed on the interface; this parameter will not be sent to the image quality value in the platform. If the input value is valid, the image quality parameter interface setConstract etc. is called through the interface to send the image quality parameters to the image display processing layer. At the same time, in PictureModeParam, an independent file can be created here to implement the recording of the image quality parameter list data in the current mode. Finally, the newly created image quality adjustment template is saved as an independent file in the U disk / palette / directory. If the image quality adjustment template needs to be called later, the corresponding independent file of the image quality adjustment template can be retrieved from the U disk / palette / directory.
